THE RISK

High Risk

Releasing a collection from memory is an operational action that affects the runtime state of the database system — it unloads the collection so it can no longer serve queries until reloaded. This is not a simple read, write, or delete of data, but an execution of a system-level operation that changes the availability state of the collection.

HOW TO CONTROL MILVUS_RELEASE_COLLECTION

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Server for Milvus, and nothing reaches the server without passing your rules. This is the rule we recommend for milvus_release_collection:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "milvus_release_collection": {
      "limits": [
        {
          "counter": "milvus_release_collection_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

milvus_release_collection stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
